Pigmentation
Chlorophyll
au- Seedlings emerge golden yellow. Lethal - survives 1-2 weeks.
chi-6- Plants emerge light green. Older plant parts darken to normal.
cov- Foliage dark blueish green.
gp- Pods yellow. New growth, peduncles and sepals often yellowish so character may be discerned before pods develop.
le- Internodes short, with zigzag pattern. Pleiotropic effects: flowering time slightly later: shorter roots; leaf and pod colors darker.
o- Foliage and pods yellowish green. With I, cotyledons very light yellow. Young pods with green stripe along upper and lower suture.
pa- Foliage, pods and immature seeds medium green color (freezer type). Pa lighter green (canner type). See also vim.
py- Precocious yellowing. Foliage color normal until near maturity. Then foliage and pods rapidly turn yellow. Stem base pale.
vim- Foliage and pod color medium dark green; Vim medium color. See also pa.
wex- All parts of plant light blue grey. Plants weak and unproductive. Pollen grains small and frequently in tetrads. Quasi-epistatic to wax genes.
Anthocyanin
a- Absence of anthocyanin production.
b- Controls 5-hydroxylation of the B-ring of anthocyanins. Flowers pink. Pleiotropic on axil and seed coat pigmentation.
d - Axil pigmentation. d gives no pigmentation. Dco conditions single pigment ring around axil: Dw conditions a double ring.
rups- Anthocyanin spots on pods with rups. Probable pleiotropic effects on inflorescence and stem.
Shape
Leaflet
af- Leaflets converted to tendrils. Stipules not affected.
apu- Leaf pulvini replaced with petiolules.
art-1- Swollen nodes. Short upper nodes. Undulate leaves.
bulf- Periphery of leaflets necrotic, brown and papery. Reduced vigor and seed set.
cri- Leaves, stipules, flowers and pods crinkled with tissue foldings. Peduncles and petioles shortened. Leaflets appear narrow, with nearly parallel sides.
curl- Leaves strongly curled. With a, leaves slightly curled.
sil- Leaflets and stipules sinuate. With af, adventitous tendrils arise from clefts in distal portion of stipule. With wlo, stipule tip waxless. With wb or wsp, stipule tip waxy.
td- Leaflets with no dentation or occasional single tooth.
tl- Tendrils converted to leaflets. Heterozygous Tl/tl recognizable by flattened tendrils.
uni- Leaves in uni plants include unifoliate to trifoliate. Flowers pistiloid and sterile. Leaves in uni plants with tac allele with apical leaflet and 0 to 2 tendrils. tac allele doesn't effect flowers.
Stem
art-1- Swollen nodes. Short upper nodes. Undulate leaves.
creep- Stem in vegetative phase creeping - completely prostrate. Grows normally after onset of flowering.
fa- Fasciated plants. Fused stem - little branching high on plant. See also fas.
fas- Fasciated plants. Fused stem - little branching high on plant. See also fa.
le- Internodes short, with zigzag pattern. Pleiotropic effects: flowering time slightly later: shorter roots; leaf and pod colors darker.
pro- Basal branches grow at 45 degree angle.
rms- Many basal branches - ramosus type. Stems seemingly more lignified.
Stipule
coch- Stipules either simple and spatulate with long stalk, or like a compound leaf. Expression varys with ontogenic stage. Flowers open, allowing some natural cross fertilization.
cri- Leaves, stipules, flowers and pods crinkled with tissue foldings. Peduncles and petioles shortened. Leaflets appear narrow, with nearly parallel sides.
sil- Leaflets and stipules sinuate. With af, adventitous tendrils arise from clefts in distal portion of stipule. With wlo, stipule tip waxless. With wb or wsp, stipule tip waxy.
st- Stipules lanceolate, slightly bent, with surfaced reduced by about 80%.
win- Plants generally free of wax. Similar to wel but win plants become slightly waxy with age. Leaflet blades on first 5 to 6 nodes somewhat unexpanded or conduplicate.
Tendril
af- Leaflets converted to tendrils. Stipules not affected.
sil- Leaflets and stipules sinuate. With af, adventitous tendrils arise from clefts in distal portion of stipule. With wlo, stipule tip waxless. With wb or wsp, stipule tip waxy.
tl- Tendrils converted to leaflets. Heterozygous Tl/tl recognizable by flattened tendrils.
uni- Leaves in uni plants include unifoliate to trifoliate. Flowers pistiloid and sterile. Leaves in uni plants with tac allele with apical leaflet and 0 to 2 tendrils. tac allele doesn't effect flowers.
Size
Leaflet
lat- Increases leaflet and stipule area to double size.
Root
le- Internodes short, with zigzag pattern. Pleiotropic effects: flowering time slightly later: shorter roots; leaf and pod colors darker.
Stem
le- Internodes short, with zigzag pattern. Pleiotropic effects: flowering time slightly later: shorter roots; leaf and pod colors darker.
Stipule
lat- Increases leaflet and stipule area to double size.
st- Stipules lanceolate, slightly bent, with surfaced reduced by about 80%.
Surface
Epidermis
Aero- Grey spots on foliage, due to air space under epidermis.
Arg- Silvery grey foliage due to air space under epidermis.
Waxes
sil- Leaflets and stipules sinuate. With af, adventitous tendrils arise from clefts in distal portion of stipule. With wlo, stipule tip waxless. With wb or wsp, stipule tip waxy.
wa- Stipules on both sides, leaflets on underside, and pods without wax. Stem and upper side of leaflets with nearly normal wax.
was- Stipules on both sides, leaflets on underside, and pods without wax. Stem with about 20% of normal wax.
wb- Stipules on both sides and underside of leaflets nearly waxless. Pods without wax. Stem and upper side of leaflets with nearly normal wax.
wel- Absence of wax on all parts of the plant, although a trace of wax may occur on the stem. Epistatic to wa, was, wb, wlo, wp, wsp.
win- Plants generally free of wax. Similar to wel but win plants become slightly waxy with age. Leaflet blades on first 5 to 6 nodes somewhat unexpanded or conduplicate.
wlo- Upper surface of leaflets without wax. Other parts normal wax.
wsp- Upper surface of leaflets with normal wax. Other parts waxless.
